An apparatus for removing impurities from water and/or wastewater and a method of installing a fluid distribution system in the apparatus. In the most preferred form of the invention, the fluid distribution system is an air scour system for directing air through the filter bed to assist in cleaning of the filter bed to remove impurities trapped in the filter bed during a service run. In the most preferred form, the method of installing the fluid distribution system in the filter bed is performed by imparting a force to the filter bed to permit the fluid distribution system to be installed in the filter bed without removing media. The fluid distribution system is preferably configured to permit the fluid distribution system to be readily installed in the filter bed and at an optimum orientation.

A microparticle and/or nanoparticle separation, filtration and/or enriching device. The device comprises a flow passage through which can be directed a liquid suspension supporting microparticles and/or nanoparticles therein, and at least one packed bed of particles physically retained within the flow passage through which can pass therethrough the liquid suspension. The device further comprises an ultrasonic actuation system for mechanically activating the or each packed bed during passage therethrough of the liquid suspension.

Exemplary systems and methods relating to washboxes are described.

An apparatus includes a waste-movement system having a bed-support assembly configured to receive, contain and support an aquarium bed of an aquarium. A vibration-source assembly is configured to be positioned relative to the bed-support assembly. The vibration-source assembly is also configured to selectively generate and transmit vibrational energy to the aquarium bed while the aquarium water is made to flow. This is done in such a way that the gravel of the aquarium bed becomes, at least in part, spaced apart (at least in part) from one another; and the aquarium water, at least in part, moves (at least in part) the liquefied waste and the solid waste through the aquarium bed from a first interior section to a second interior section of the aquarium.

A fluid filtration system is disclosed herein. The filtration system includes a main tubular housing defining an interior chamber and having an outlet opening at a top end thereof and an inlet opening at a bottom thereof. A tubular inlet housing extends vertically into the interior chamber of the main housing through the inlet opening of the main housing. The tubular inlet housing has a hollow interior filled with shards of permanent magnets, a plurality of outlet portals located in the interior chamber proximate the bottom of the main housing, and an inlet opening at a bottom thereof. An inlet conduit is connected to the inlet opening of the tubular inlet housing. An adjustable fluid pump and can force the fluid from a supply of fluid to be filtered upwards through the inlet conduit at varying speeds. A permeable but compact horizontal layer of medium capable of trapping particulates is provided in the interior chamber of the main tubular housing adjacent the tubular inlet housing. The layer includes filtering particles that are attached to the magnets. Forces of magnetism produced by the shards of permanent magnets and gravity constrain the horizontal layer of filtering medium to maintain in place the layer of filtering particles. The adjustable fluid pump, an air pump connected to the inlet conduit, or electromagnets or vibrators mounted on an outer surface of the main housing can be used to disrupt the compactness of the layer of filtering particles to permit trapped particulates to be released and washed away from the layer of filtering particles.
